## What it does

Give the agent this skill and it follows a set order: add the Info.plist key, ask for authorization, build the presentation and attributes, call `AlarmManager.shared.schedule(id:configuration:)`, then watch `alarmUpdates` until the scheduled ID lands in the state you want. Firing alerts reach the Lock Screen, the Dynamic Island, StandBy and a paired Apple Watch, and they get past Focus and Silent mode.

One section covers the `.alarm` versus `.timer` choice: clock time with weekday repeat on one side, an always-visible countdown from a duration on the other. State transitions get the same treatment, including which calls throw when the alarm is not in the matching state.

Skip `NSAlarmKitUsageDescription` or lose the user's permission and nothing gets scheduled — the app needs recovery UI instead of a silent no-op. Countdown UI you can style lives only in a Widget Extension built on the same `AlarmAttributes<Metadata>`, because the ringing alert itself is system-drawn. Deployment target has to be iOS 26 or newer; older ones have no AlarmKit at all.

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/dpearson2699/swift-ios-skills/tree/HEAD/skills/alarmkit/SKILL.md

## When to use it
- schedule an alarm that still fires in Silent mode
- build a countdown timer with pause and resume
- show the remaining time on the Lock Screen and in the Dynamic Island
- attach a snooze button with system-handled behaviour
- catch a missing authorization request during review

## Example prompts
- Build an AlarmKit alarm that repeats on weekdays with a snooze button.
- Add a countdown timer and render it in the Dynamic Island through a Widget Extension.
- Check that the app asks for authorization before `AlarmManager.shared.schedule(id:configuration:)`.
